Personally my favorite platformers are 2D ones so this one will be top on my list... only thing that could be better would be a new 2D Metroid... Fusion really got me pumped for a new Metroid, but in 2D.

Please provide a level editor for users to create and share custom Mario levels. Hackers have been doing it for years by tampering with retro titles; Nintendo needs to enable this in-game to satisfy the hardcore fanboys once-and-for-all. Think about it: Little Big Planet (PS3), Mario vs. Donkey Kong 3 (DS), Pushmo (3DSware) all had level editors, and the grid system in 2D Mario titles is perfect for level-editing.

No more New Super Mario Bros style games, they are too bland & easy. I want a real sequel to Super Mario World. A massive map & heaps of stages, with hidden routes & secrets. I want a Mario game which encourages exploration again.

Mario 64 & World are my favs. I do like the new Mario games, but they have nothing on the epicness of World & 64. NSMB, as good as it was felt like Super Mario Bros Lite to me. Galaxy had tiny planets with little to bugger all exploration, more get from point A to B. Still awesome games though.Ive been playing Nintendo since I was 5 & im 27 now, so im a picky bastard these days lol

At the risk of putting a downer on this news (and I'll probably get crucified), I worry that they're releasing too many Mario games of late. Super Mario is my favourite franchise, but I don't want them to churn out too many in quick succession and lead to overkill (Sonic...), burn-out is death for franchises. It seems to have become a yearly release of late (something that other franchises are always criticized for). Having to wait for a new game (like we have for a new main Mario entry in the past) is a good thing, it makes it all the more special when it arrives. I don't have 3D Land yet because I've played a Mario every year for the past four, I've only just played the last one and I haven't built up a hunger for a new one yet (and by the time I do, they'll be another 3DS one and a Wii U one). I could understand if 3D Land bombed, but it's selling really well, so I am surprised by this announcement, particularly so soon. Maybe the financial situation really is bad.

@StarDustBut the overwhelming success of the recent 2D Mario games was precisely because they didn't innovate. They simplified and went back to their retro roots. The term "innovation" is very much overused when it comes to the appeal of Nintendo's games.

A level editor is what I've been dreaming of since Super Mario Bros. 3. Make it like the Mario vs DK games (and less like LittleBigPlanet) and I'll buy it day one. The level editor in the Mario vs DK games is incredibly easy to use. LittleBigPlanet, on the other hand, is too complex for my liking.

Genius. I always considered SM3DL as a semi-side-scrolling platformer so it's nice to have a new 2d stylee, 100% side-scrolling Mario game in the pipeline. Now for next year, a full-on free-roaming 3d Mario game....

Brand new platformer, with time trial mode with online leaderboards and the option to play as Mario, Luigi, Peach, Toad, and whoever else like in Super Mario 2, along with a level editor with online share, and Retro Mode, which gives you the option to 8-bitify (lol) the game once you have completed it once.

This is definitely exciting news but I can see why Haywired is worried about the series burning out due to games in the series being released so often especially as Super Mario 3D land wasn't in the same league as the other 4 3D Mario platformers. Hopefully it won't be a similar case with this next 2D Mario game. I hope that Nintendo are really imaginative with the worlds this time as in NSMBW the level design may have been some of the best ever but the worlds had the same themes as its predecessor just in a different order. I don't mind if some of the worlds have the same themes as worlds in the previous 2D game in the series but not all of them.

You can't have enough Mario. I hope that this 2D title goes a different path than the New Super Mario Bros. formula and tries something new. As is the answer most of the time when it comes to new games, E3 will reveal more.

NSMB Mii ideas shown on Wii U... promise of 2D mario on 3DS in the same fiscal year that the Wii U will launch... I'm thinking these titles might converge into a showcase of how the 3DS should work with the Wii U. No?

You could do multiplayer on the 3DS like NSMW, but also share in a big screen if playing with the Wii U. While regular play on the Wii U would maybe have a hot seat passing of the Wii U controller so players could dive down into secret areas on their screen, you could have multiple people play that way when they introduce a 3DS into the mix.

Explaining that all though makes it sound a bit too complicated to pull off. But it seems to me that a NSMB game could be completely solid in time for the Wii U launch and here is an official announcement about a similar game coming to the 3DS in the same time frame. How often does Nintendo promise something like this. Unless we are talking launch date, right?

Plus, Smash Bros was touted as showcasing this ability but it will be a long ways off. Nintendo needs a big popular title to get people on board with the idea.

At E3, Nintendo could show it off working with the 3DS and convince many people to pick up a 3DS before the Wii U launch... well, me at least. lol.

edit:@Rapadash6Looks like I took too long to write my post, but I'm glad I'm not the only one thinking this

Why do people keep saying that the New Super Mario Bros. games aren't like Super Mario World? Out of the old 2D games I would say NSMB DS/Wii are most similar to Super Mario World. How exactly similar do you want them to be?

But in all seriousness; I hope Nintendo includes a level editor, improves the graphics, and includes online multiplayer (if it turns out to be another NSMB game). If it's a non-NSMB game, then that would be interesting to say the least.

I could've sworn last year Myamoto said he was workIng on a 3D Mario Title and a 2D Mario title. Either way it is awesome and has been developed for some time now if what I say is true. @Nintendo: keep em coming.

Awesome, I love the sidescrolling Mario games. A 2D platformer with 3D visuals can looks absolutely amazing if done right. I've always wanted to play Donkey Kong Country Returns on Wii in 3D cause that game has such a great amount of depth.

This will hopefully be a awesome 3D title. Also, I want them to do 4p online CoOp this time. Would be great to be able to play the singple-player with 4 other people online

Just like SM3DL was "a 3D Mario game that plays like a 2D Mario game", why shouldn't the concept be in reverse?

How about a Luigi platformer? LM2 is great, but when was the last time we saw Luigi in a platformer of his own? Like 20 years ago (idk exactly). Waluigi/ King Boo can be the main atagonist, and the game takes place in Sarassaland, where Daisy was introduced.

All that with an included level designer, and you got yourself a masterpiece

However, the release should be pushed to as far as 2013. There are too many great title out this year.

I honestly hope it doesn't end up treading the same ground as the New Super Mario Bros. games. I loved New Super Mario Bros. Wii, and I still do, but the next 2D Mario needs to really up the ante now that it's got competition like Donkey Kong Country Returns, Kirby's Return to Dreamland, and Rayman Origins to compete with.

If you want to talk about something different, then how about a game like Super Mario Land and Six Golden Coins? It could have the return of Wario, Tatanga, Daisy, and classic enemies and bosses from both games. I can dream.

While I'd like to see this one have more of a Super Mario World feel, it would also be nice to see Wart return too! Has to be, by far, the most underused baddie from the Mario universe. Unless there's an appearance I'm not thinking of, he hasn't been seen since Super Mario Bros. 2, has he? And this is the year for 80s Nintendo character comebacks, so...

But, if Nintendo is going chronologically by their old games, this is Super Mario World's turn. You could say New Super Mario Bros. equals original Super Mario Bros. New Super Mario Bros. Wii had four different playable characters, making it SMB 2 (then again, it also had aspects of 3 and World). I don't even need to point out that Super Mario 3D Land equals SMB 3. That means for this new Super Mario, it's time to return to Dinosaur Land.

If I remember correctly, didn't somebody at Nintendo say that they would like to make a super mario world sequel, when the 3DS was first announced at e3 two years ago? A real sequel not a spinoff of sorts like yoshi's island. That game was great tho.

So many questions now.Will the WiiU title be pushed back 'cause of it ? Will there be a heavy use of WiiU <-> 3DS connection ? Will you be able to download the full game to your 3DS when you buy the WiiU game ? Will it be an eShop game ? Will it still feel nostalgic enough or maybe even a bit stale ? Will it be in SMW's or NSMB's vein or have completely different level themes ? Will they finally bring back the World Maps from SMB3 or SMW ? Maybe even make a combination of the two ? Will Nintendo still provide new titles in other underused franchises that have huge gameplay and sales potential ?

... i'm kinda disappointed. as much as i love sidescrolling mario games, nintendo struck gold with sm3dl and i wish they would expand on that game... and maybe wait a little while.. i mean its not that i dont like to have mario games asap but generally when a series goes yearly it indicates that sales have been low recently and they're tryin to milk the fans that have been buying games. i know that's not true of mario but still...

@Nilkad_Naquada Nintendo has stated that both 2D and 3D mario games will coexist from Super Mario Galaxy 2 and NSMBWii on. So essentially they are two different takes on the same fundamentals. The 2D Mario games have become more casual affairs, and while 3DLand blended both, it will be interesting to see how they differentiate this new game. But as I stated before.... LEVEL EDITOR! HEAR THAT NINTENDO? Level... Editor...

i hope it's new super mario bros. 3ds!i hope it's 2d with graphics better then new super mario bros. wii, with great 3d effects like mighty switch force,and mutant mudds. cause the 3d effects works amazing with 2d games!!and a level editor where you can share levels with friends and post them to a nintendo server so the whole world could share levels would be awesome!plus a QR code option would be great!and then nintendo could put out a free official level every week for a year!!

then i think it should have 4 players local co-op cause if eveyone has there own 3ds it would let us explore different parts of a level without having to stay right next to each other,think how amazing that would be!!!then i would hope for a 4 player co-op online but i would be happy with 2 player co-op online and 4 players locally!!

and i know the new super mario bros. are alot like the old games but thats what i like cause my little brother and i have been playing mario games sense the nes days!!so when i got new super mario bros. wii my brother stayed over my house for the weekend and we had so much fun playing the game for hours at a time like we were kids again!plus i haven't laughed so hard playing video games like we we did playing new mario bros. wii cause it would be funny as hell when one of us would accidentally kill the other one or we would laugh or asses off when one of us would do something stupid and die!

it was so much fun and it was so funny and then sometimes my girl would jump in and make it more fun!!and thats what nintendo and mario games are about fun!!and if you are a more serious gamer you should get mario galaxy 1 or 2 thats why i was happy they made 3 mario games for wii cause one was more serious and one was more for fun!!!

If I could have things my way, the new game would be in the vein of Super Mario World, with very high quality sprites (maybe like high quality animation, akin to Wario Land: Shake It!). Hey, I can dream...

This might just be referring to the 3DS Paper Mario title. The Super Mario series is becoming like Mega Man: almost 1 every year. Don't milk one of your prized franchises to death, Nintendo, if you are reading this!

If the game takes after SML/2(read: SML, &/or SML2:6GC), then the game will essentially be taking after SM Bros., &/or World respectively, as that's what those games took after, for the most part. Even though I've never played SML, I know that there were dis-similar parts of that game, like the plane level(SkyPop, I think?), stuff like that.

SM3DL didn't fully take after SMB3, since flight wasn't available. Nintendo had flight in SM64(i.e 3d space), so the only reason I can imagine flight was skipped in 3D Land, was due to the nature of the levels being semi-straightforward/linear, & that flight would have allowed most of the levels' layouts to be skipped over.

I personally, wanna see a platformer, where Luigi is the star, rescuing Daisy. Or at the very least, a return of Wart, or finally bringing over Tatanga, Wario, Waluigi(edit, & Daisy) into the main Mario canon games, instead of leaving Waluigi to spin-offs, & Wario/Tatanga to the meta(sub-) series.
